Title: Apparatus for the manufacture of cigar-fillers
IPC: A24C1/08
Filed: 1935-02-20
Abstract: 436,626. Cigar - making machines. DRESSELHUIJS, A. M. J., 12, Goudriaankade, The Hague. Feb. 20, 1935, No. 5454. [Class 130] Tobacco is pressed from a hopper 23 into a slidably-mounted mould 47 by intermittently reciprocated spring-controlled fingers 21. The fingers are pivoted on a shaft 20 carried by a reciprocating rod 17, and are pushed through slits 22 into the hopper on their downward stroke and withdrawn during their upward stroke. Intermittently operated feeding-bands 31, 32 are arranged on the sides of the hopper, and an intermittently rotated roller 40 guides the tobacco into the mould, where it is severed by a cam-actuated knife 41, which closes the outlet of the hopper while a cam-actuated rod 48 slides the mould 47 over the table 19 on to supports 62 carried by a bow 53. The bands 31, 32, the roller 40, and the rod 17 are all driven from a shaft 9 carrying a pinion 10 which is intermittently rotated by a toothed segment 7 on a shaft 8. The segment 7 carries a roller 63 which engages a cam surface 64 on a lever 66, and through levers 67, 68 depresses a rod 56 to lower the bow 53 between vertical guides 60 until the supports 62 contact with the bottom of a container 73. Further movement of the rod 56 compresses a spring 59 and presses a stamp 54 through the mould 47 to deposit the tobacco filler on a wrapping-apron 82. After a spring 72 has moved the lever 66 against a stop 71 to position the stamp 54 above the mould 47 and raise the mould to the level of the table, cam-actuated levers 80 operate a roller 75, to roll the filler in a binder on a board 74.

Filed: 1928-02-22
Abstract: 312,216. Ellis, G. B., (Chemische Fabrik Gr³nau, Landshoff, & Meyer Akt.-Ges.). Feb. 22, 1928. Processes.-The outer surfaces of concrete articles are subjected, during moulding, to the products of decomposition of the alkaline hydrolysis of albuminous substances, including albuminoids, in order to delay the hardening of the outer layer so that it can be washed away to obtain a decorative effect by revealing the structure of the filling pieces. For example, the moulds may be coated with a solution of the alkaline salts of lysalbic or pratalbic acids. It is stated that the washing water which penetrates the main structure during the washing-off process causes a gradual final hardening of the exposed decorative surface.

Abstract: 689,105. Rolling sugar confectionery. SANDALL PRECISION CO., Ltd., and BARKER, A. W. June 8, 1951 [March 9, 1950], No. 5974/50. Class 87 (ii). [Also in Group XXIV] The rollers 12 of a batch rolling machine are driven by spindles having intermeshing gears 33, driven from shafts 44, 46 having gears 43, 45, respectively. The other ends of the shafts have freely mounted gears 49, 50, and clutches 53, 54 axially slidable on and rotatable with the shafts. The gear 50 is driven directly by a sprocket 78 and chain. The clutches are so intercoupled by a lever 57 that when one clutch (53, as shown) engages its corresponding gear 49, the other clutch is disengaged. The direction of rotation of each roller is periodically changed by a pin on a delay shaft 48 which engages a member 67 to rotate an element 63 and thus disengage one, clutch and engage the other. Each clutch is withdrawn sharply from its corresponding gear, when the member 67 is rotated, by a spring toggle device 76. The delay shaft 48 is continuously driven by a gear 47 intermeshing with gears 43, 45, and consists of a collar 72 fixed to rotate with the shaft and collars 71, 70, 69 freely mounted on the shaft, As the shaft rotates a pin 73 on the collar 72 engages a pin 74 on the collar 71 and so carries this collar around. The other collars have similar interengaging pins, so that eventually the collar 69, carrying the pin which engages the member 67, is rotated. The clutch element 63 has stops 85, 86 which engage a stop 84. The driven ends of the rollers may have bearings in spherical recesses in levers (Fig. 3, not shown) which may be either fixed or capable of being moved towards or away from each other. A spring may be provided in the lever system to pull the levers towards one another, and the levers may be moved into a fully separated position in which the spring occupies an over dead centre position and ceases to draw the levers together. Many of the details of the machine may be as described in Specification 689,104.

Title: Improvements in or relating to the insertion of rivets or the like into workpieces
IPC: B21J15/34
Filed: 1937-03-02
Abstract: 491,498. Eyeleting-machines; riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and GOULDBOURN, J. March 2, 1937, No. 6166. [Class 43] [Also in Group XXII] A portable device for inserting rivets into holes in workpieces and sup porting them against clenching pressure comprises a portion 1, supported in the hands of an operator, and a rivet raceway 9 that moves to deposit a rivet on a pin 25 and is retracted after depositing the rivet, after which the rivet is inserted into a, hole in the workpiece. The pin 25 is mounted in a head 24 of the device so that the pin can yield against the action of a spring 27. The raceway 9 is pivotally connected to levers 8 and 15 which are pivoted at 4 and 13 respectively to the body 1 of the device. In operation, the handle 7 is drawn towards the handle 3 thereby raising the raceway while the pin 19 slides in the slot 21, the lever 15 being held stationary by the pin 16, a rivet 38 from the raceway being deposited on the pin 25. On further movement of the handle 7 the lever 15 turns and forces the pin 16 out of place, thus moving the raceway in a curved path from the bottom of the pin 25. When the handle 7 is released the spring 33 forces it away from the handle 3, thus moving the raceway first vertically downwards and then in a curved path to a position below the pin 25. Detachable pins 19 and 10 enable the raceway to be removed from the device and hung on to the bottom of the raceway of a rivet-loading device by a hook 35.
